National Computational ScienceUniversity of Illinois at Urbana-Champaign

Environmental Hydrology Team Meeting

• Show how the Alliance has demonstratably changed the nation’s computational infrastructure

• Show explicitly how we have empowered communities to do things better

• Focus on deployment of infrastructure

• Deploy real codes to real researchers coupled with real metrics of use

• “Harden” software to be accompanied by documentation, training, and dissemination

Educational focus secondary for this year in AT

Primary Alliance Objectives in Year 4


Purpose of Workshop

1) Learn about the current status of EH projects 2) Develop overall team goals for this year in light of

Alliance goals3) Refine SOW’s in light of team goals4) Determine current and future AT and/or EH team

collaboration5) Define expected deliverables this year both

dependence and independent of EH development6) Identify what is holding us back from reaching our

individual and group goals7) Discuss communication and reporting 8) Plan group PR9) Other ?????


Presentation Guidelines

1) Briefly summarize past accomplishments and deliverables with at most 3 to 4 bullets on 1 or 2 overheads

2) State your main goals and deliverables (and your groups specific contributions to these them) for this year. I would like at most 4 bullets here.

3) What communities will you actually impact this year and how will this be accomplished (include plans for disseminating software or interacting with communities who will benefit from your work)

4) Note who on your team will actually carry out the work and what percentage of time they will be contributing

5) Note your questions/concerns about realizing the goals and deliverables (e.g., looking for a student to work on this, work can't begin until January due to other commitments, when will a linux cluster be available for me to work on,........)

Alliance Technology Roadmap

• Capability computing– attack complex problems– move from rationing to

computing on demand• Building the Grid

– eliminate distance for virtual teams

– convert computing into a utility• Science portals

– bring commercial web technology to scientists

– build electronic research communities

• Clusters as the unifying mechanism– User wants and review
